The numerical result shows that the power flow direction is reverse to that of phase velocity.
数值结果显示了在这种波导中能量的流向和相速度具有相反方向。
To horizontal bend, the displacement of axial and horizontal direction is larger than vertical direction. The displacement of pipe is mainly caused by the impact of two-phase flow.
对于水平弯管，轴向和水平方向上的变形要比垂直方向上的大，管道变形主要是由流体对管道的冲击作用引起；
Based on a particular direction of energy flow from one phase to the next, the interaction can be expansive, destructive or exhaustive.
基于能量从一个方位流到下一个特定方位时，这种相互作用可扩张，破坏抑或耗尽。
